In Pixar's Cars 2, the World Grand Prix promotes the alternative fuel called Allinol.
Miles Axlerod presents Allinol as a clean, modern fuel and encourages racers to use it in the international competition. The fuel becomes central to the film's mystery when several cars suffer dangerous failures. The spy characters investigate whether the incidents are accidents or part of a deliberate plan.
The story uses Allinol to connect racing, energy politics, and espionage. Axlerod's public campaign makes the fuel appear environmentally attractive, while the plot gradually reveals that its real purpose is much more sinister. The name is fictional and belongs to the Cars universe.
Allinol is not the same as Rust-eze, which is a bumper-ointment brand and McQueen's racing sponsor. Dinoco is another fictional fuel and petroleum brand in the series, but it is not the World Grand Prix fuel promoted by Axlerod.
